It may not be rocket science, but it's close. Fuel cells have been used to power spacecrafts for years and on Saturday, April 16, 2011, Chicago-area middle school students will use fuel cells to power model cars at equipment manufacturer Case New Holland (CNH) in Burr Ridge, Ill., as part of the Chicago Regional Science Bowl, sponsored by the U.S. Department of Energy (DOE) and Argonne National Laboratory.

Water and oil may not mix, but, like two boxers nearing the end of the final round, they can get awfully tangled up. Now, Michigan Technological University scientists Yoke Khin Yap and Jaroslaw Drelich have created a filter that separates the two substances as quickly and cleanly as a ref breaking up a clinch.

Transistors are commonly used in electronics as switches to turn an electrical current on or off. For applications that require a very large ratio between the on and off current, however, it is necessary to use mechanical 'reed' switches, in which magnetic fields physically move metallic wires (or reeds) towards and away from electrical contact points. As devices become more compact, these mechanical switches need to be miniaturized into small packages, without sacrificing performance.

Atomic force microscopy (AFM) is a highly sensitive form of microscopy that makes it possible to map a surface with near-atomic resolution. Shaw Wei Kok and colleagues from A*STAR's Singapore Institute of Manufacturing Technology have now developed an AFM measurement method that can improve the sensitivity of the technique even further.

Read moreMicroscopically tiny ferromagnetic platelets exhibit a phenomenon which could be exploited in the future for particularly stable magnetic data storage: so-called magnetic vortex cores. Five years ago, researchers at the Max Planck Institute for Intelligent Systems found a way to reverse the magnetic field needles despite their stability using only a tiny amount of energy so that their tips pointed in the opposite direction. Such a switching process is necessary to enable the vortex cores to be used in data processing. The Stuttgart scientists have now discovered a new mechanism which makes this switching process at least 20 times faster and confines it to a far smaller region than before.

Elektronenmikroskope nutzen einen fokussierten Elektronenstrahl, um winzige Objekte sichtbar zu machen. Wird das Instrument mit einem Gasinjektionssystem kombiniert, lassen sich Materialproben manipulieren und nanometerfeine Oberflaechenstrukturen darauf "schreiben". Empa-Forschende haben mit Wissenschaftlern der EPFL diese Methode nun genutzt, um Laser zu verbessern.
